My room stops at 5.1. Its too small for rear channels or another sub. If I get a new house with a larger "Theatre Room" in the future I can see myself going to 7.2. Unless I win the Lottery thats all I can imagine reasonably doing.

I mean really? Height and Width Channels? Perhaps adding a Centre channel to the rear as well... What is that? 12 channels? I think anything over 7 (non-LFE) channels would make for really minor improvements.
